What temperature should I be getting on i7 ivy bridge 3770k with stock heatsink?
This is what I get on my 3770K
Using IBT 2.53 (Intel Burn Test) and RealTemp 3.70
Previous 3770K: Stock speeds, stock cooler, room 25c, case open
Standard: 95c to 102c within a minute or so. Stopped at about 3 mins.
Maximum: 105c within 2 mins (after 16 GB is fully loaded) and then the cpu starts to throttle. Stopped when I saw throttling.
New 3770K: Stock speeds, stock cooler, room 26c, case open
Standard: 87c to 92c, but took about 5 mins to get there. Ran for 15 mins. Mostly stayed below 90c
Maximum: 91c to 97c, but also took about 5 mins to get there. Ran for 10 mins. Mostly stayed in the 87-91 range.
So I have no idea what was the deal with my previous 3770K and stock cooler. Maybe it was a defect in the copper mating surface of the previous cooler. But these temps make me happy as I know that IBT causes a lot of heat and I won't see this normally.
I did a 5 min test using the latest 64bit Blender 3D with the standard current benchmark blend file. And it utilized all 8 thread. Total utilization was 75-80%, temps ran an average of 75c. Max peaks which didn't happen often, was 80c.
So now that I am happy about my chip. My Noctua NH-D14 is on it's way. Should be here Tuesday. After that I will do my same test at stock speeds. While I normally use (and have) Arctic Silver 5, many people are showing tests that put the Noctua compound within 1 c of the AS5. So I will likely just use the Noctua paste that it comes with.
And now to buy the rest of my case fans and hopefully I have time next week to set my slight overclock and move on with my life. And I will likely buy the extra Intel warranty, though I likely won't need it as I plan on staying around 4.2 to 4.4 Ghz. Maybe 4.5 Ghz if the temps are decent.
I've got a 3770k with a NH-D14. It's currently running at 4.4Ghz and with prime95 running it gets to 80-85 C. Probably 4.5 will also run within acceptable limits. The maximum build-in OC on my board of 4.8 is pushing it too hard for air cooling (unless i start tweaking voltages down)
Funny thing is the second I stop prime95 the temp drops back to 40 C. I heard the intel used subpar thermal paste in their ivy bridges, which my lead to bad heat spreading in heavy load scenarios.

Same problem here. i7 3770K with the stock cooler. It started out with an idle of 38c, but one of the plastic pins appeared to pop out (which is weird because I screwed them in perfectly). Then it started jumping 38-42 (to even 51c on core #0). Then I took it off, cleaned the thermal compound and put in Arctic Silver 5. Still did not solve the problem, even though the stock cooler was tight. I'm thinking the plastic pins just aren't good. So I'm putting in a Tt 2.0 Performer LC. Really hoping this will fix it. The CPU is seated perfectly, so maybe it's a bum stock cooler. (Hopefully).
